How to Grow Salvia Victoria Blue

Salvia Victoria Blue

Salvia farinacea 'Victoria Blue'

flower

Victoria Blue is a compact, heat-tolerant salvia cultivar prized for its deep blue-purple flower spikes and silvery foliage. It blooms continuously from early summer through frost and grows as a tender perennial often treated as an annual in cooler climates. The plant attracts hummingbirds and pollinators while requiring minimal maintenance.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily (partial afternoon shade tolerated in hot climates)

💧

Water: Moderate watering; allow soil to dry slightly between waterings. Once established, quite drought-tolerant. Reduce watering in winter for perennial plants.

📏

Spacing: 12 inches

📅

Days to maturity: 60-90 days to first flowers from transplant

🌱

Planting depth: Surface sow or barely cover seeds (light-dependent germination); transplants at same depth as nursery container

Soil

Type: Well-draining loamy or sandy soil

pH: 6.0-7.5

Amendments:

Compost or aged manure for fertility Perlite or coarse sand for improved drainage Avoid heavy clay or waterlogged soils

Growth Stages

Seedling

2-3 weeks

Tiny green leaves emerge with fuzzy texture characteristic of salvias. Plants are delicate and require consistent moisture without waterlogging.

Start seeds indoors 6-8 weeks before last frost. Maintain 70-75°F soil temperature. Provide bright, indirect light. Keep soil consistently moist but not soggy.

Vegetative Growth

4-6 weeks

Plant develops bushy, compact form with gray-green, velvety foliage. Stem elongation occurs rapidly as temperatures warm. Multiple shoots branch from the base.

Transplant outdoors after last frost danger passes. Pinch back growing tips at 6-8 inches to encourage bushiness. Water regularly and apply balanced fertilizer every 2-3 weeks.

Flowering

8-10 weeks until frost (or year-round in warm climates)

Dense spikes of deep blue-purple tubular flowers emerge from branch tips. Flowers are arranged in whorls along the spike and attract hummingbirds and bees.

Deadhead spent flower spikes to encourage continuous blooming. Reduce nitrogen fertilizer to promote more flowers over foliage. Water during dry spells. Plants bloom continuously in warm weather.

Maturity

Continues until frost or indefinitely in zones 8-10

Plant reaches full size (typically 18-24 inches tall and wide) with abundant flowering. In warmer zones, may continue blooming through winter.

Maintain deadheading for continuous blooms. In zones 8-10, reduce water in winter and cut back by one-third in early spring. Watch for spider mites in hot, dry conditions.

End of Season/Overwintering

Until next growing season

Plants slow flowering as temperatures drop below 50°F. In cold zones, foliage blackens and plants die back. In warm zones, plants may remain evergreen or semi-evergreen.

In zones 3-7, pull plants after frost and compost. In zones 8-10, cut back hard in early spring (6-8 inches above soil) and reduce water. Can be overwintered indoors in a cool, bright location.

Fun Facts

🌱 Victoria Blue was selected and introduced by the seed company Fleuroselect for its superior compact habit and vibrant flower color compared to other Salvia farinacea cultivars.
🌱 The common name 'mealy sage' refers to the white, mealy coating (farina) on the plant's stems and calyxes that gives it a silvery appearance.
🌱 Salvia flowers have a highly specialized structure that causes hummingbirds' foreheads to brush against pollen when they feed, making them exceptional pollinators for the plant.
